Re: VM options to run Geronimo

Maxim Berkultsev Thu, 30 Mar 2006 08:24:21 -0800

Hi, Matt!

I've tried

java -server -XX:-PrintTenuringDistribution -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -jar ./bin/server.jar

since it seems too long to wait for the problem so I've limited VM with the default heap size. Please see a portion of log below.

It looks as if the heap was taken up intensively.

For an OutOfMemory problem please see the stack trace further.

Best regards,
